@ThePowerofDreams: 25 kilos of fuel cost about 0.875s per lap in lap time. Still, I would advise against trying to guess fuel loads at this stage.
@ThePowerofDreams: Which is why I would advise against jumping to conclusions about potential lap times at this stage without knowing the fuel loads.
@ThePowerofDreams: It backs up what we've been saying for some time: Mercedes has only shown a fraction of their pace this pre-season. But it's still very difficult to make any direct comparisons. As others have said, I would be surprised if Mercedes didn't have the edge at the first race, but mainly because they were so dominant last year.
Back on track, Grosjean, Rosberg, Kvyat and Nasr are on track. Bottas has just come back to the pits.
Rosberg has improved to a 1:24.321 now. Still on the mediums.
@MrTuK: Actually a lot of people did complain. And stopped watching.
It looks like Vettel has gone back out after a long spell in the garage at Ferrari.
@Thestyb: Mercedes has provided 2015 engines to its customers since the start of testing. They have been quiet about token spend, but they say almost every part of the engine is new in some way.
@JacobRosencrantz: No, you've misunderstood the way it works. The tokens aren't split among the teams, they are spent on the engine which is then supplied to the teams. And tokens are only spent on performance upgrades, they can upgrade on the basis of reliability, cost or safety at any point without spending tokens. So just because all parts have been changed doesn't mean they were all changed for performance reasons.
@Alan: You have also misunderstood a lot of what has been going on the last few years.
Red flag ten minutes from the end. Nasr has stopped at Turn 6.
It looks like that red flag is going to end the session and this week's test. Just three minutes left on the clock. Tick tock, tick tock...
@kathy: It did come back out Seb completed another five laps just now. A stop of that length is most likely an engine or gearbox change.
We have got green flags again for the final minute of this week's test
Rosberg, Kvyat, Bottas and Vettel all head back out for one last blast
The chequered flag comes out and with it the second pre-season test of 2015 comes to an end.
Thanks for joining us this week. We'll have a full session report and we are gathering quotes and information from the paddock as I type. Check back on the website later for more reaction to today's event and the week's test in general.
We'll be back next week for the final pre-season test of the year (Thursday to Sunday). I hope you'll join us.
